Modelling Correlation Coefficients:

Correlation factors:
rDifficulty : 0.5634468
rMajor : 0.5752469
rMode : 0.1712162
rUnit : 0.3080475
rCultural : 0.3231582

By comparing the correlation coefficients of each stress factors, we clearly see stress caused by major of the student and the difficulty of their study units has the highest correlation with overall stress.

Linear Modeling:

Satisfied assumptions made:
* Linear relationships between independent (Majors & Study Difficulty) and dependent variables (Overall stress)
* Independency of students’ stress levels
* Equal spread in the y-direction shows homoscedasticity of data

Since both the aforementioned stressors have higher correlation association to the students’ overall stress compared to the other stressors, we can suggest that mainly certain majors contribute most significantly, followed by the courses’ difficulty.
